Artificial insemination, ICSI procedure »
One of the largest series reporting results using IVF/ICSI was from Van Steirteghem et al. at The Brussels Free University in Brussels, Belgium. In their preliminary report on 150 couples who underwent 150 consecutive treatment cycles, 1409 oocytes were injected and 830 were successfully fertilized for a fertilization rate of 59 percent. A total clinical pregnancy rate of 35 percent was achieved. The fertilization rate in this study was not influenced by the standard semen characteristics of concentration, motility, and strict criteria morphology. In another largest case serie on ICSI …

Until recently, the clinical application of direct injection of a single sperm into the cytoplasm of an oocyte during IVF was not shown to be feasible. The demonstration of fertilization and live births by Palermo et al. in 1993 was the first successful application of ICSI. Since that time, ICSI has been performed extensively in multiple centers to treat patients with severe male factor infertility. To date, the success of ICSI procedures has been related to several factors: (1) the viability of the spermatozoon, (2) the quality of the oocyte, …

Intra-cytoplasmic sperm injection (ICSI) is a relatively new but well-established procedure first performed in 1992. The procedure was developed to help male factor infertility. The procedure involves injecting a single sperm into the cytoplasm of each egg using a fine glass needle. The first ICSI baby was reported in 1992. The ICSI has largely replaced the two previously developed procedures, PZD (partial zona dissection) and SUZI (subzonal insemination) because it achieves much higher fertilization rates.

Artificial insemination, GIFT procedure »
In patients undergoing the gamete intra-Fallopian transfer (GIFT) procedure, a prospective study was perfonned to establish the predictive value of attempting in-vitro fertilization (IVF) using extra oocytes obtained at laparoscopy and also the value of transferring the resulting embryo(s), in conjunction with GIFT, in the same treatment cyde. The GIFT procedure was performed in 50 treatment cycles involving 43 patients, of whom 20 have achieved clinical pregnancy with an overall success rate of 40% per treatment cycle. In 38 of these patients, one or more extra oocytes were available and …
